O le Raspberry Pi 4 Model B (Raspberry Pi 4 Model B) o le lona fa o augatupulaga o le Raspberry PI aiga, o se microcomputer maualuga, taugofie. E sau ma le 1.5GHz 64-bit quad-core ARM Cortex-A72 CPU (Broadcom BCM2711 chip) e matua faʻaleleia ai le mana galue ma le tele o galuega. O le Raspberry PI 4B e lagolagoina le 8GB o le LPDDR4 RAM, o loʻo i ai le USB 3.0 port mo le faʻavaveina o faʻamatalaga faʻamatalaga ma, mo le taimi muamua, faʻafeiloaʻi le USB Type-C power interface mo le vave faʻatonuina ma le mana.
O le faʻataʻitaʻiga o loʻo faʻaalia ai foʻi fesoʻotaʻiga lua Micro HDMI e mafai ona tuʻuina atu i le taimi e tasi le vitio 4K iugafono i mataʻitusi e lua, ma faʻamaonia ai mo fale faigaluega lelei poʻo nofoaga autu multimedia. Feso'ota'iga uaealesi tu'ufa'atasi e aofia ai le 2.4/5GHz lua-band Wi-Fi ma le Bluetooth 5.0/BLE, fa'amautinoa le fetu'una'i feso'otaiga ma feso'ota'iga masini. E le gata i lea, o le Raspberry PI 4B o loʻo tumau pea le pine GPIO, faʻatagaina tagata faʻaoga e faʻafesoʻotaʻi le tele o masini ma gaioiga mo le faʻalauteleina o atinaʻe, faʻapitoa mo le aʻoaʻoina o polokalame, iot projects, robotics ma le tele o mea faʻapitoa DIY.
